It was a nice sunny day in the Nation of Fontaine, you were viewing the the city from afar on a tall hill. Feeling the wonderful wind, nice air, and sounds from the environment.

You see a mountain that has a mechanical base on top of it, it seems that they are keeping something secret inside, and you know what it is, Prototype-331. The Large mechanical titan, built to protect all of Teyvat of the upcoming 2nd war. Built by Neuvillette and his greatest engineers.

You kept looking at the base until... The lights inside of the base went out. That's weird, it seems like a power outage occurred in there and the inside of the mountain. Then you heard a loud mechanical rumbling sound, and it came from the mountain base... Prototype-331 is already ready? But the war hasn't even started...

Then it happened, a large red beam inside of the mountain came out, and it was slicing a portion of the mountain inside, vertical. Then the beam stopped, and two large mechanical arms came out and grabbed onto the edges, then it fully revealed its self, it roared very loud. But you heard something else in the roar, a dragon's roar, it sounded very similar to the description of Durin's roars... Could it be? Did Durin hijacked both pilots and now has full control of the machine...? You heard some information a while ago that Neuvillette used Durin's brain for Prototype-331 power. Durin was stopped by Dvalin and the Anemo Archon, Barbatos or Venti. They destroyed its body, but never it's brain and conscious.

It looked at the sky, looking at the sun while covering the shining bright lights with his claw like hand... Then it looked down at the people of Fontaine, they're panicking. It did a mechanical evil laugh and roared at them. Durin consciousness has full control of Prototype-331, and ready to get revenge. It used its Proton Scream Beam onto the people, and then onto the buildings.

Prototype-DURIN is ready to get revenge, on those who stopped him... Fontaine's second Prophecy, has begun...
